Mechanics

Mechanics is the branch of physics that studies the motion of objects and the forces responsible for causing or changing that motion. It is basically grouped into Newtonian Mechanics and Quantum Mechanics, both of which are important.

It is the oldest and most foundational area of physics, forming the basis of virtually every engineering and applied science discipline. Additionally it is is divided into kinematics — which describes how objects move — and dynamics — which explains why they move as they do. At advanced levels, it extends into rigid-body mechanics, fluid mechanics, and relativistic mechanics.

You can find the applications of mechanics in almost every field:

• Civil engineering — designing bridges, buildings, and structures that withstand forces
• Aerospace — calculating rocket trajectories, satellite orbits, and aircraft flight
• Automotive engineering — braking systems, crash safety, and suspension design
• Biomechanics — understanding how forces act on the human body during movement
• Sports science — optimizing athletic performance using projectile motion and impulse
• Robotics — planning and executing precise mechanical movement in machines

The core ideas of mechanics — Newton’s laws, force, energy, momentum, and gravitation — explain an enormous range of phenomena using a small set of powerful principles.
